Behind each sample a reference 1455600100020 foil, either In or 58Ni was placed. Two experiments 1455600100021 used single pelet at 0 deg with In monitor, third 1455600100022 experiment used pelets at four different positions 1455600100023 to cover incident energy range 2.42 - 2.74 MeV and 1455600100024 58Ni monitor. 1455600100025 DETECTOR (SCIN) Beta activity of irradiated samples was 1455600100026 measured using liquid scintillator counter (LSC). 1455600100027 To measure the solely beta activite reaction 1455600100028 products 35S and 32P, the pellet NaCl was first 1455600100029 dissolved in 4 ml of water, and then 16 ml of 1455600100030 Ultima Gold XR scintillation cocktail was added 1455600100031 to the sample and mixed before being counted in 1455600100032 the LSC. The LSC used in this study was the 1455600100033 PerkinElmer TriCarb 2910 TR. 1455600100034 (HPGE) HPGe detector was used for measurement of 1455600100035 monitor reactions 1455600100036 METHOD (ACTIV) Activation method was used 1455600100037 MONITOR (49-IN-115(N,INL)49-IN-115-M,,SIG) 1455600100038 (28-NI-58(N,P)27-CO-58,,SIG) 1455600100039 58Ni(n,p)58Co reaction was used for relative 1455600100040 cross section determination in the whole energy 1455600100041 range. 1455600100042 MONIT-REF 1(,R.Capote+,J,JAI,9,1,2012) 1455600100043 ERR-ANALYS (ERR-1,,1.0) Systematic uncertainty in sample wight, 1455600100044 which was in reality much lowwer than 1%. 1455600100045 (ERR-2,,1.)
